So NOX's messenger is a fairly generic method for communicating with external applications over a socket. Built on top of this is jsonmessenger which communicates JSON messages over a socket.
If you specifically want to use protobufs (and not JSON messages), then you'd want to use the plain messenger. However, the plain messenger is not exposed to Python -- only jsonmessenger is. So I think your options are: 1) Use JSON messages instead of protobufs, and just use jsonmessenger 2) Expose messenger to Python, and then use this to send/receive protobufs 3) Use protobufs and roll your own method for communicating with your external application (probably using Twisted) -- Murphy On Dec 20, 2011, at 11:02 PM, Harshil Anil Kumar Shah wrote: > Hi Murphy. > Yes, I have external C++ module which I want to communicate with Nox python > module using protobuf.
